Phonons, the collective excitations responsible for heat transport in crystalline insulating solids, lack electric charge or magnetic moment, which complicates their active control via external fields. This presents a significant challenge designing thermal equivalents of basic electronic circuit elements, such as transistors diodes. Achieving these goals requires precise and reversible modification conductivity materials. In this work, continuous tuning local charge-transfer SrFeO

In this work, we reported the fabrication of improved Au/ZnO/Si resistance switching (RS) devices achieved by introducing buried cone-like Au nanoparticles (NPs). The NPs were facilely obtained thermally annealing a thin film grown on Si substrate, which did not influence subsequent growth ZnO films. Electric measurements verified typical RS behaviors in devices, are related to recovery and rupture conductive filaments due electric field-driven oxygen vacancy migration. Notably, COMSOL-based electrostatic field simulations Au/ZnO/Au structures have shown that an enhanced local with 4.5 times enhancement was produced at tip NPs, facilitated vacancies migration around NPs. Accordingly, controlled formation proposed NPs/Si greatly window, stability, endurance. results work may pave way for high-performance oxide-based future.
